Question about Canon CanoScan FB320P Flatbed Scanner

1 Answer

ScanCraft CS-P always says there isn't a scanner connected or that there might be something in the parallel port

But the scanner is connected and I don't know what a parallel port even is. All the plugs are connected and everything, so I'm confused.

    Um the outcome was that it wouldn't work. The program said there was no scanner connected even though there was. It also said something about a TWAIN source, like a problem with the connection, but I don't know how to set that up and I think I might be supposed to.

Evening MCRmyFranKIE, A parallel port is commonly known as a printer port or LPT1 port. Before USB ports existed scanners frequently used them to connect to computers. The connector on the PC is typically *D* shaped and contains two rows of 25 pins, about 1 ¾ inches wide. Questions for you: -Are you using that kind of cable or a USB cable? -Have you tried uninstalling and reinstalling the software following the instructions yet? Once you give us some more information we can continue.

    Wow, that was the quickest anyone has ever responded ? live time!

    OK, USB is far easier to install than parallel port. I forgot to ask if you are using Windows XP but for now I?ll just assume that is the case. Unplug the USB cable from your computer and uninstall the software. Reinstall the software from scratch following the instructions exactly. One thing to note is that the scanner should stay unplugged from the PCs USB port until prompted by the software or the instructions. Once you are you should see a series of pop-up detecting the hardware unless we have a problem.

    -If nothing happens test to make sure your scanner is getting power. There should be an LED to indicate that.
    -If still nothing try unplugging the USB cable from your scanner and insert it into another USB port on your PC. Make sure you are plugging directly into your PCs USB port not a USB hub.
    -If still nothing try another USB cable, preferably one you know works.

    If you get this far and still nothing let us know what happened at each step, what operating system you have, what kind of PC (Dell, HP, etc.) and any other information or history that seems pertinent.

    OK, again assuming you?re using XP click on Start, settings, and control panel. Find and double click on the icon that?s labeled *Add or Remove Programs*. When the Add or Remove Programs box appears it will list all the programs installed on your computer. Now this is the tricky and potentially dangerous part, you have to go through the list and one by one highlight the canon scanner programs (there may be one or a couple) and click the Change/remove button to the right. Chances are the right one will contain the words Canon and/or scanner.

    Once you?ve done this go ahead and try what I suggested previously. Its getting late here so I?ll be off-line for about nine hours.

  • tomj23 Jan 18, 2007

    the original software that came with the scanner. Did you in fact install scanner software?

  • tomj23 Jan 18, 2007

    OK, if that is the original install CD it should say Canon scanner installation CD on it. If it does then all you have to do is unplug the USB cable from the PC, pop the CD in the PC and follow the installation instructions.

    If the CD doesn?t say Canon scanner installation CD (or something thereabouts) it may be an extras CD in which case you?ll need to download software from the Canon site.

    I take it this scanner is something you just recently got, probably used correct?

Am looking at buying a friends 320 scanner, He cant find the booklet or cd 4 it. also doesn't have the parallel cable eather. Can i get this from the company? Also I havw windows xp. will this work on...

First you would need to make sure you have a parallel port on your computer, because if you don't, you would need to get an adapter of some sort for either a p2p or usb port, whichever you prefer. I'm not sure if you can get a parallel cable from the manufacture, but you could probably find it on eBay. With an older scanner and a newer computer, you can probably just plug it in and it will work, but if you need the software, go here:

Hope this helps!

No parallel port on my computer. USB -parallel

This scanner is an old one so it has only parallel port. You can connect it to any USB with the converter you mentioned and should be working. Did you connect the power supply at the scanner too? It is nesessary for the scanner in order to take power.

Mustek 1200 is an old scanner so it's normal that it hasn't usb connection. You have to buy a USB to parallel port adaptor (about 10Euros) in order to connect the scanner with your laptop. Of course you 're gonna use the power supply that you 've got with the scanner in order to power up the scanner.

Usb 1.0 or usb 2,flatbed scanner compatability

Find a USB device, such as a memory-stick, that is "USB 2.0" and connect it to a USB port. If Windows XP pops-up a window ("this device will perform better when connected to a USB 2.0 port"), then you have connected it to a USB 1.1 port.

Yes, you can connect a scanner, if it has a USB connection. Not all laptops have a parallel-port ("old-style" printer) port, but some scanners require a parallel-port.

Cable connectivity with my laptop through a "parallel to usb cable". My laptop has no parallel port but only usb ports.

make sure you follow this step :
1. install driver USB to Paralel port (LPT1) before the cable connected to PC
2. After the driver installed, install the cable - and it supposed to be detected
3. the last think u have to do is install the scanner/printer driver

if it is not work, i guess the problem is on the USB to paralel adapter, or the driver not installed correctly

Hi my HP scan jet 3400c cannot turn on. what is a problem.

The scanner have two ports to connect to PC, USB and Parallel.

It has no Power switch.

Disconnect all cables from your scanner (USB/Parallel and power.

Plug power cable to the scanner, and then plug the power supply to an outlet.

Does it turn on ?

If not, than check the power adaptor.

If it turns on, then turn off your computer, plug the USB/Paralel connector to the scanner and to your PC and turn on your PC.

You should know that you can use only one connection for your scanner at a time, USB OR Parallel.
Parallel for under Windows98, and USB for Win98 and above.

Need help to hook up IBM color flatbed scanner

Attach one end of a parallel port cable to the parallel (printer) port on your computer and the other end of the cable to the computer port on the rear of the scanner. If you have a printer connected to your computer, you must disconnect the printer cable from the computer before connecting the scanner cable.
If you have trouble attaching a cable connector to a port, be sure that you are connecting the correct end of the cable to the correct port.
IF. . . you want to use a printer WITH your scanner, attach one end of the printer cable to the printer port on the rear of the scanner and attach the other end of the cable to the printer.
Plug in power cord and then power up PC.
Power on scanner. Install drivers. Restart PC to activate EZ Station buttons.

Initialization failed - Unable to acquire TWAIN-compliant device



I have seen your message stating that "Initialization failed - Unable to acquire TWAIN-compliant device" error is received when trying to connect USB-Parallel type to your Laptop.


Well,  Printer  Panasonic UF4100, recommends to use only " Printer/Scanner Interface as Bi-directional Parallel (IEEE1284) " means you need to use Parallel cable to connect Printer to the Computer/Notebook.  You may receive some communication error messages if you are using a  "PORT REPLICATOR CABLE"( USB TO PARALLEL connector).  The error message that you have received is related to the communication error. Futher, if you use same USB- Parallel cable for long time the Printer Hardware functionality might go bad, since Printer memory gets confused and will not read or detect the Cable , since it is not a cable to use  mentioned by Panasonic Manufacturer.


Let me tell you, general functionality of Printer like Printing would work even if you use USB-Parallel cable. But it is not a case with Scanner and Fax functionality.


Hence, I recommend you to use only Parallel cable to connect your Printer to the Laptops.


I hope that this will resolve the issue for you.


You can email me at if you need further assistance.

How to hook up?

This scanner may have a parallel and a USB port. Use the USB port, if it exists. If not, connect the scanner to the parallel port, then connect the printer to the pass-through port on the scanner. This can be problematic, requiring changes to the BIOS and driver difficulties. A USB scanner is a better solution, and they are cheap nowadays.
